The Governor's Citadel and Palace in Bastia dates back to the 14th century. The former palace of the Genoese governors houses the municipal museum, formerly the Ethnology Museum of Corsica.Abutting the old fortress tower and decorated with a 14th-century campanile, the Palace of Governors over the centuries guarded Terra Nova and beyond the ramparts of the Old Port. The city has undertaken a program of renovation of the palace under the direction of architects Cléris Daniel and Jean-Michel Daubourg.
Besides the renovation of the palace the work helped to rebuild the part of the monument that was destroyed in 1943 during the fighting for the liberation of Corsica. The new museum was inaugurated in June 2010. The museum collections are organized into four themes: birth and urban growth, centre of power, cultural centre, and the Palace of Governors. The turret of the submarine Casabianca was preserved in the courtyard until the renovations.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
